IMPROVEMENT IN PIN-RAILS FOR VESSELS.

Specication forming part of Letters `Patent No. 200,613, dated February ,26, 1878; application filed October 15, 187,7.

To all whom it may concern:

Beit known that I, THoMAs W. HYDE,of

Bath, in the county of Sagadahoc and State.

of Maine, have invented certain new and useful Improvements in Pin-Rails for Vessels 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the drawing is shown a top view of a I portion of the deck of a vessel, a mast, and a i have therefore, of necessity, been so placed as that the mast or lower part thereof was passed through the railwhen it was stepped or placed in its position. This was inconvenient, and might lead to serious difficulty if the placing of the rail in its position were overlooked or forgotten.

I make the rail in two or more parts, so that it can be placed around and fitted to the mast after it is in position. I make the rail of castiron, and so enhance its cheapness, and the rapidity with which it can be constructed.

When the rail is made whole or of onev piece, it is likely not to be adapted or tted to the mast; or, if so fitted when new, it may become loose in time by wear, from shrinkage of the mast, and various causes. Once loose, itis plain that the whole iron rail can only be tightened yby wedging or chocking, or some such method.

My improved rail, being in two or more pieces, can always be easily and readily tight:- ened up to the mast. I

In the drawing, a shows the parts of the pinrail formed in such wayas may be most suit-V able for its intended use. At the joints or junctions b of the severalparts are provided notched cleats c. These cleats receive the rail at these points, bind it firmly, hold the parts together, and' the entire rail in place. Thus there is produced a cast-iron pin-rail made in parts, for the masts of vessels, with a capacit-y of being iitted and adjusted to the mastone that can be readily applied, tightened, and well held in position.

l What I claim as my invention, and desire to secure by Letters Patent, is-- l A pin-rail composed of the two or mor parts, of cast metal, in combination with the notched cleat o, attached to the mast and holding the rail, as herein set forth. l

In testimony that I claim-the foregoing as my own I aiix my signature in presence of two witnesses. l

THOS. `W. HYDE.
